EKG RHYTHMS

QuestionAnswer
sequence for interpretation of rhythm strips: Rhythm-regular or irregular Rate-6sec or300,150,100,75,60,50,43 P waves-if there is one for each QRS. are the normal in size and shape PR interval- normal .12-.20 QRS complex-normal .04-.11
normal sinus rhythm NSR or RSR Rhythm- regular Rate-60-100bpm P waves-normal and before each QRS PR interval- normal .12-.20 QRS complex- normal .04-.11
sinus bradycardia Rhythm- regular Rate- 40-60bpm P waves- normal and before each QRS PR interval-normal .12-.20 QRS complex- normal .04-.11
sinus tachycardia Rhythm- regular Rate-100-150bpm P waves-normal and before each QRS PR interval-normal .12-.20 QRS complex-normal .04-.11
sinus arrhythmia Rhythm- irregular Rate- 60-100pbm P waves-normal and before each QRS PR interval-normal .12-.20 QRS complex-normal .04-.11
premature atrial contractions - PAC Rhythm- underlying rhythm regular Rate-underlying rhythm P waves-normal and before each QRS PR interval-normal .12-.20 QRS complex- normal .04-.11
wondering atrial pacemaker - WAP Rhythm-regular/slightly irregular Rate-60-100can be slightly slower or faster P waves- vary in size and shape PR interval-varies QRS complex-normal .04-.11
atrial flutter - Aflutter Rhythm-regular but can be irregular Rate-can occur at any rate P waves-NONE saw toothed flutter waves instead PR interval-NONE QRS complex-normal .04-.11
paroxysmal atrial tachycardia - PAT or SVT Rhythm- regular Rate-greater than 150bpm P waves-normal and hidden before each QRS PR interval-unable to measure QRS complex-normal .04-.11
atrial fibrillation - Afib Rhythm-irregularly irregular Rate-can occur at any rate P waves-NONE small f waves PR interval-none QRS complex-normal .04-.11
premature ventricular contractions-PVC Rhythm-underlying rhythm regular Rate-underlying rhythm P waves-NO Pwaves PR interval- QRS complex-WIDE .12 higher
ventricular tachycardia - Vtach Rhythm-regular Rate-100-250bpm P waves-NONE PR interval-NONE QRS complex-wide and bizarre
ventricular fibrillation - Vfib Rhythm-chaotic Rate-to fast to count P waves-NONE PR interval-NONE QRS complex-chaotic
asystole Rhythm-NONE Rate-NONE P waves-NONE PR interval-NONE QRS complex-NONE
bundle branch block check lead V1 for a QRS greater than .12
left bundle branch block if the QRS is mostly negative (QSwaves)
right bundle branch block if the QRS is mostly positive (R wave)
premature junctional rhythm - PJC Rhythm-underlying rhythm Rate-underlying rate P waves-negative absent (in QRS) or after QRS in twave PR interval-short if present QRS complex-normal .04-.11
junctional rhythm Rhythm-regular but can be slightly irregular Rate-40-60bpm P waves- PR interval- QRS complex-
accelerated junctional rhythm Rhythm-regular but can be slightly irregular Rate-60-100bpm P waves-negative,absent (in QRS)or after QRS in Twave PR interval-short if present QRS complex-normal .04-.11
junctional tachycardia Rhythm-regular but can be slightly irregular Rate-greater than 100bpm P waves-negative absent (in QRS) or after in Twave PR interval-short if present QRS complex-normal .04-.11
1st degree AV block atrioventricular blocks Rhythm-regular Rate-can occur at any rate P waves-normal PR interval-prolonged grater than .20 QRS complex-normal .04-.11
type 1-2nd degree AV block atrioventricular blocks Mobitz 1 Weneckebach Rhythm-regular except when drop occurs Rate-can occur at any rate P waves-more Pwaves then QRS PR interval-longer longer drop QRS complex-normal .04-.11
type 2-2nd degree AV block atrioventricular blocks Mobitz 2 Rhythm-usually regular Rate-can occur at any rate P waves-more Pwaves than QRS PR interval-consistent QRS complex-normal .04-.11
3rd degree AV block atrioventricular blocks Rhythm-regular Rate-very slow P waves-more Pwaves than QRS PR interval-inconsistent QRS complex-normal .04-.11

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
